- XRD Analysis
- Hectorite + quartz (m) + calcite (L) + dolomite (s)? (before acetate treatment) (Norma Vergo) This sample(SHCA-1.Ac-B) was treated with acetate to dissolve carbonates. There is no fizz with HCl. Clay grains have sweeping extinction, quartz present but no evidence of calcite or dolomite. All consistent with a fairly pure sample of hectorite. G. Swayze.
